True
When a solid freezes, it contracts making the molecules inside get closer together which makes the volume smaller.
A skeletal muscle connects two bones together by the joint and when the muscle contracts it brings the two bones closer together. These skeletal muscles moves the bones.
when the muscle shortens (contracts), the two bones come closer together, isometric contraction excepted.
when it is cold the cremaster muscle contracts and draws the testes closer to the body to keep them warm.
No, because we cannotsee the black hole itself. We can however infer that things are falling in from the massive amounts of energy released from the presumed accretion disks as they get hot from the friction of matter crowding closer together before it can disappear into a black hole.
when a muscle contracts or shortens the attached bones are pulled closer to each other
The water which was originally in a liquid stage, turns into a solid when it freezes. The particles in the water come closer together, therefore, the water contracts. This is not true. Most liquids do this when they freeze but water expaneds.
When water molecules are moving closer together in the air it is called
When grains move closer together, eliminating spaces, they have compacted.
Closer
It depends.
the particles get closer together because my class just talked about that stuff!!
